VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 537,100,,dated April 9,1895. Application filed March 27, 1894. Renewed February 18, 1896.$erial No. 538,885 (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK A. YOUNG, of Richmond, Raycounty,'Missouri, have invented certain new and useful Improvements inVehicle-Brakes, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof. I

My invention relates, to vehicle brakes, and has for its object toproduce a brake mechanism which is simple, strong and durable; which ispositive and reliable in action, and which may be operated from variouspoints; furthermore, to produce a mechanism of this character which maybe easily secured in or removed from position, and which is inexpensiveof construction.

With these objects in view, the invention consists in certain peculiarand novel features of construction and combination of parts, ashereinafter described and claimed.

In order that the invention may by fully understood, reference isto behad to the, accompanying drawings, in .which Figure 1. is a verticallongitudinal section of a wagon, and showing my improved mechanismapplied thereto in operative position. Fig. 2. is a side elevation of myimproved brake-mechanism, and showing it operatively applied to a wagon,and showing it connected with a hand lever of difierent constructionfrom that shown in Fig. 1. Fig. 3. is a perspective view of thebrake-mechanism in operative position. Fig. 4. isadetail view. Fig. 5.is a view. of my improved brake-mechanism, as applied to ahay-rack, Fig.6. is a detail perspective view of a construction slightly difierentfrom that shown in Fig. 3, and Figs. 7, 8, and 9, are detail views ofvariousparts.

In the said drawings, 1 designates the rear Wheels of a wagon truck, and2 designates the axle connecting the same.

3 designates the front wheels, 4 the axle connecting the same, and 5 thelongitudinally extending reach which connects the front and rear axlesin. the ordinary manner.

6 designates the hounds, converging forwardly from the rear axle andsecured to opposite sidesof the reach in the ordinary manner, andboltedor otherwise rigidly secured upon said hounds, is a semicircular casting7, the open side of which is disposed forwardly, and is secured inanysuitablemannor to the transversely extending bar 8. This bar restsupon the upper side of the hounds and the reach, and is secured firmlyin this position by the U-shaped clips 8, which em brace the hounds attheir lower and opposite sides, and projecting up through the saidtransverse bar, have their screw-threaded ends engaged by retaining-nuts8". It is' to be understood, however, that this bar may be securedrigidly upon the hounds and reach in any other suitable manner withoutdeparting from the spirit of my invention. A rock-shaft 9, is journaledlongitudinally of and upon the bar 8, and is provided at each end withthe depending arms 10, terminating in books, which pivotally engage thestaples or loops 11, projecting upwardly from thebrake-beam 12, which isarranged a suitable distance in advance of the front peripheries of therear wheels, and carries at each end the brakeshoes 13, in the ordinarymanner. Arranged longitudinally of and vertically beneath the center ofthe reach-bar 5, is a semicircular casting 14, which depends from andhas its ends rigidly secured to the semicircular casting 7, and theunder side of the cross-bar 8. A lever, which operates in a verticalplane, is pivoted at 15 to the said casting 14, and is composed ofsimilar arms 16, extending diverg'ently upward from the pivotal point 15so as to embrace loosely the opposite sides of the reach-bar 5, and theupper ends of these arms are connected by the bolt 17, and the lowerends by the bolt 18. A link-bar 19' is pivotally mounted at one end uponsaid bolt 18, and is secured at its opposite end to the brakebeam, aboutmidway its length. A longitudinally extending bar 19, is pivotallyconnected at its rear end upon the bolt 17, and projecting forwardlytherefrom, extends beneath the guide-loop 20, projecting upwardly fromthe cross-bar 8.

It will be apparent from the foregoing, that the forward movement of thebar 19, will rock the lever composed of the similar arms 16,

and cause the brake-shoes to engage the periphery of the rear wheels.Depending from, and extending longitudinally of the bar 19, is a loop21, and extending transversely of the machine and through said loop, isa lever 22, which is pivoted at 23 to the semicircular casting 7,adjacent to one end. It will be apparent from this construction, thatthe operation of thelever22, in thedirection of the arrow, Fig. 3, willmove the bar 19 forwardly, and apply the brakes as above explained.

The casting 24 is bolted upon the upper side of the bar 19, and isformed with a recess 25 in its rear end; said recess being theequivalent of the loop 21, and engaging this recess, and extendingtransversely of the wagon, is a lever 26, the free or handle end ofwhich projects slightly beyond the side of the wagon, and this lever ispivotally connected at 27 to the semicircular casting 7, and adjacent toone end thereof. By the operation of this lever in the direction of thearrow, Fig. 6, it will be apparent that the bar 19'is moved as aboveexplained, and the brakes applied, and in order to secure the brakesagainst the wheels, the casting 7 is provided with the toothed segment28, which is engaged by the lever 26; said lever being of spring-metal,so that it shall hold its position when once in engagement with thistoothed segment.

In Fig. 1, 29 designates a vertical shaft, which is mounted at the frontend of the wagon'body, and this shaft carries, at its lower end, acog-wheel 30, which meshes with the teeth of a rack-bar 31, which ispivotally connected at 32 at its rear end, to the front end of thelongitudinally extending bar 19, and this rack-bar is supported inoperative position at its front end and held in engagement with the co-wheel 30 by a guide'casting 33, which is secured to the bottom of thewagon. 34E designates a lever, which is pivoted to operate in a verticalplane, to the upper end of the shaft 29, and this lever engages theracksegment 35, secured to the foot-board of the wagon. The lever 34, ispreferably in the form of a crank-handle, so that by operating it in onedirection or the other, the brake may be applied or thrown from itsengagement with the wheels.

In Fig. 2, 36 designates alever, which is pivoted at the side of thewagon, and engages the rack-segment 37, in the usual manner, and thislever 36, is connected through the medium of the link-bar 38, with thefree end of the transversely extending lever 22, so that by theoperation of the lever 36, the brakemechanism may be operated asrequired.

In Fig. 5, a hay-rack is shown mounted operatively upon the truck, andthe lever 39, pivotally mounted at the front end of the hayrack, ispivotally connected through the medium of the link-rod 40, to the frontend of the longitudinally extending bar 19, so that bythe operation ofthe lever 19 the brake-shoes may be thrown into or out of engagementwith the rear wheels.

In the practical construction of this brakemechanism, either one oranother of the three means of operating the brakemechanism from thefront end of the wagon, will be employed in connection with thelaterally extending lever 26'; said lever being provided for use whenoccasion may demand, such, for instance, as when the wagon is upon adescend ing plane, and the person in charge is walking at one side. ofthe wagon, when he may apply the brake without remountin From the abovedescription, it will be apparent, that I have produced a brake-mechanismwhich may be applied to any of the ordinary forms of wagons now in useeasily and expeditiously; which is positive and reliable in operation;which may be operated from various points, and which is simple, durable,and inexpensive of construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
